REMOVABLE BRACE BAR FOR TYEPEWRITER TABLES.

Application filed January 19, 1918.

To all whom it may concern:

Be it known that 1, Farmers M. MARSH, a citizen of the United States,residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented certain new and useful Improvements in Removable Brace Bars forTypewriter Tables; and 1 do hereby declare the following to be a full,clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to removable brace bars for typewriter tables ofthe folding type and is an improvement on my prior Patent, #1206570,issued to me November 28th, 1916 and the primary object of the inventionis to simplify and cheapen the cost of manufacture of the article and atthe same time render the same stronger and more durable.

"With these and other objects in view the invention consists in thenovel construction, arrangement and formation of parts as will behereinafter more specifically described,

' claimed and illustrated in the accompanying drawing, forming a partthereof, in which Figure 1 is a perspective view of the improved table,

Figure 2 is a vertical longitudinal section through the improved tableshowing the brace bar in position and one of the legs locked thereto andthe opposite leg in its sprung position,

Figure 3 is a detail sectional view illustrating the improved jointbetween the brace bar and the leg of the table.

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral1 generally indicates the table which includes the top 2, having thelongitudinal and transverse cleats 3 and 1 secured to its lower surface.Hingedly secured to the transverse cleats 1 are the right and left handframes 5 and 6, which carry the supporting legs. The frames areconnected to the cleats 4 by means of any preferred type of hinges 7 andthese hinges are secured to the inner meeting surfaces of the frames andcleats. The rear supporting legs are designated by the numeral 8 andthese legs are provided with sockets 9 in their inner opposed faces. The

Serial No. 212,645.

brace bar is designated by the numeral 10 and extends from one leg tothe other and is formed slightly longer than the distance from one legto the other, the purpose of which will hereinafter more fully appear.The brace bar has formed on its ends the outwardly extending centrallydisposed nobs, pins or lugs 11 for engaging the sockets 9. The frames 5and 6 are so formed that when it is desired to place the brace bar 10 inposition, the frames are sprung apart and the lugs 11 are then placed inthe recesses 9. Hooks or tie rods 12 are pivot-ally secured at theirupper ends as at 13 to the brace bar 10 adjacent each end thereof, andthese hooks are adapted to engage headed pins 14: carried by the rearlegs 8 of the frames 5 and 6. Owing to the fact that the brace bar 10 isformed slightly longer than the distance between the frames 5 and 6, theframes normally tend to spring away from each other and thus when it isdesired to hook the hooks 12 over the pins 1& it is necessary to presson the ends of the legs and force the same inwardly towards each otherand thus the hooks hold the legs against outward movement and hold thebrace rod 10 in position. The brace rod 10 acts as a fulcrum for therear legs 8 when the same are being bent inwardly towards each other toallow the hooks to be positioned over the headed pins 14:.

From the foregoing description, it can be seen that an improved brace isprovided for typewriter tables which can be readily placed in positionby springing the legs of the table away from each other and then held inposition by means of the hooks 12.

By this construction a novel arrangement is provided which allows thetable to be readily and quickly assembled and presents a rigid structurein which the parts are absolutely prevented from becoming disassembled.

In practice, I have found that the form of my invention, illustrated inthe accompanying drawings and referred to in the above description, asthe preferred embodiment, is the most eflicient and practical; yetrealizing the conditions concurrent with the adoption of my device willnecessarily vary, I desire to emphasize the fact that various minorchanges in details of construction, proportion and arrangement of partsmay be resorted to, when required without sacrificing any of theadvantages of my invention as set forth.

l/Vhat I claim as new is A typewriter table comprising a rigid top,laterally flexible legs or a; width approximately equal to the width ofthe top and hinged at their upper inner corners to the underside of thetop, said legs being pro vided below their upper ends with socketsopening out through their inner sides, a brace bar reinovably positionedbetween the legs and provided at its ends with knobs located in thesockets, the brace bar being slightly greater in length than thedistance between the hinged upper inner corners of the legs to exert aconstant outward pressure upon the upper portions of the legs, and tierods connected to the bar and to the legs below the bar to exert aconstant inward pressure on the lower portions of the legs, said tierods having detachable connection with the legs to permit the bar to beremoved and the legs folded one against the other beneath the top andthe outward pressure exerted by the bar upon the upper por-- tions ofthe legs and the inward pressure exerted by the tie rods upon the lowerportions oi the legs holding the upper ends of the legs in full contactwith the underside of the table and preventing accidental displacementof the bar and accidental disengagement of the tie rods from the legsand preventing any relative movements between the parts of the table.

In testimony whereof I afiix my signature.

Farmers M. MARSH.
